BISSELL MYair® personal air purifier provides Simply Clean Air™ from a trusted brand in homecare. We designed this portable air purifier to be compact, so it fits in your home's smaller spaces, but it's also packed with plenty of air purifying power when it comes to indoor air care. It has a 3-in-1 high efficiency, activated carbon and pre-filter that captures at least 99.7% of 0.3 micron particles on sleep mode, including smoke, dust, pollen, and dander. Plus, since it has three filtration technologies in one, you only have to replace the one filter when the filter change indicator activates. Its 3-in-1 filter pulls air in from 360 degrees to remove irritants, allergens, and odors before releasing clean air out from the top at one of the three fan speeds that can be set via the intuitive LED display.
